A method allows a designer to implement software for a wide variety of variant host architectures, without excessive usage of host memory, nor sacrificing the capabilities of high end versions of the variant architectures available. The method is based on providing an initialization module of the software to host memory. A portion of the initialization module determines the host architecture. Based on the determined host architecture, the unneeded portions of the initialization module are freed, and the needed portions are relocated into a contiguous memory space to minimize host memory usage. Any location dependent entries in the needed portions of the program are then updated based on the relocation. The initialization module includes a plurality of code blocks, each of which is optimized to a particular variant architecture. When the variant architecture of the host is identified, those code blocks which are optimized to the identified host are selected and the other code blocks are freed. The selected blocks are then relocated to optimize host memory usage.

A method for initializing software in a host data processing system, the host having any one of a plurality of variant architectures, comprising: loading into host memory a software module including a set of code blocks, each code block adapted for at least one of the plurality of variant architectures, wherein the software module further includes data for identifying locations of code blocks, and location-dependent entries within code blocks, based on the identified variant architecture; after loading the software module, executing an identifying portion of the software module to identify the variant architecture of the host data processing system; after loading the software module, executing a selecting portion of the software module to select a subset of the set of code blocks adapted for the identified variant architecture, including accessing the data in response to the identified variant architecture to identify selected code blocks; placing the subset within the host memory in contiguous memory locations and updating location dependent entries within the subset including accessing selected code blocks and updating location-dependent entries in selected code blocks; and freeing memory locations of the software module in host memory outside the contiguous memory locations.
